色彩心理学

True orange embodies enthusiasm, creativity, and adventure. It stimulates mental activity and social interaction, making it a favorite in creative industries. Orange is highly visible and conveys confidence without the aggression of red, bridging warmth and energy.

Design Usage

Medium orange excels in CTAs, pricing highlights, and gamification elements where excitement is desired. Tech companies and SaaS products use it to differentiate from the dominant blue of their competitors. It requires careful contrast checking since mid-range orange can fail WCAG on light backgrounds.
